Dispenser having valves actuated by yoke shaped lever
US 3651991 A
Abstract
A dispensing device for beverages consisting of two fluids wherein both are to be dispensed substantially simultaneously, comprising a pair of fluid lines with a valve in each one, each valve having an actuating means, the actuating means consisting of a yoke mounted on the body of the device and adapted for pivoting motion with respect thereto. The yoke has an upper portion which bears against the actuating means when said yoke is pivoted to cause the valve to open. A second yoke is provided which bears against only one of the valve actuators so that one of the fluids can be dispensed without the other. Resilient return means is provided urging the actuators into the closed position and the seal is maintained by the pressure of the fluids in their respective fluid lines.

[451 Mar. 28, 1972 DISPENSER HAVING VALVES ACTUATED BY YOKE SHAPED LEVER Primary Examiner-Stanley H. Tollherg Anomey--Biennan & Bierman, Harry C. Bierman and Jordan B. Bierman [57] ABSTRACT A dispensing device for beverages consisting of two fluids wherein both are to be dispensed substantially simultaneously, comprising a pair of fluid lines with a'valve in each one, each valve having an actuating means, the actuating means consisting of a yoke mounted on the body of the device and adapted for pivoting motion with respect thereto. The yoke has an upper portion which bears against the actuating means when said yoke is pivoted to cause the valve to open. A- second yoke is provided which bears against only one of the valve actuators so that one of the fluids can be dispensed without the other. Resilient return means is provided urging the actuators into the closed position and the seal is maintained by the pressure of the fluids in their respective fluid lines.

in addition, a mixing device is disclosed inorder to provide the more viscous of the two fluids from adhering to the spout of the device.

32 Claims, 7 Drawing Figures M Egg, Emil PATENTED HA8 2 8 m2 SHEET 2 OF 2 DISPENSER HAVING VALVES ACTUATED BY YOKE SHAPED LEVER The present invention is directed to a dispensing device for beverages, more particularly to a soda fountain dispenser intended primarily for use in dispensing carbonated beverages made from syrup and soda.

It is among the objects of this invention to provide a mixed beverage dispensing device which is easily operated and requires no highly specialized delicate equipment.

It is also among the objects of this invention to provide a mixed beverage device wherein the operator can with one hand dispense either the mixed beverage or plain soda.

It is further among the objects of this invention to provide a mixed beverage dispensing device which produces a good mixture between the two fluids and prevents sticking of the more viscous fluid to the device itself.

. Other advantages of the device will become apparent from the following description and the accompanying drawings in which like reference characters refer to like parts.

FIG. 1 is a side elevation of the device;

FIG. 2 is an enlarged view similar to that of FIG. 1 partly in section with some parts broken away for clarity;

FIG. 3 is a sectional view along line 3-3 of FIG. 2;

FIG. 4 is a view along line 4-4 of FIG. 2;

FIG. 5 is a sectional view along line 55 of FIG. 2;

FIG. 6 is a sectional view along line 6-6 of FIG. 4 with some parts broken away for clarity; and

FIG. 7 is a sectional view along line 7-7 of FIG. 2.

Dispenser 1 is provided with hood 2 and front 3 attached to body 4. Soda line 5 and syrup line 6 having soda inlet 7 and syrup inlet 8 respectively are connected to dispenser 1. Each of lines 5 and 6 leads into a chamber 10 via a nozzle 9. Valve closures 11 are mounted in chambers 10 bearing against valve seats 12.

Actuators 13 are connected to closures 11 by flexible valve elements 14. Elements 14 are provided with valve arms 15 which are held in place by retaining block 16. Block 16 has block openings 17 through which actuators 13 projects.

Mounted on body 4 and preferably on block 16 is combined yoke 18 pivoted at combined yoke pivots 20. Yoke 18 is provided with combined lever 23 depending therefrom and having combined lever end 24 at the lower extremity thereof. Bearing portion 41 is part of combined yoke 18 and, upon pivotal motion of yoke 18 about pivots 20, hearing portion 41 presses against actuators 13 thereby opening both the soda and syrup valves.

Soda yoke 19 is also provided on body 4 and mounted for pivotal motion with respect thereto. Preferable yoke 19 is pivoted on block 16 at one of pivots 20. Soda yoke portion 42 is adapted to press against the one of actuators 13 which controls the soda valve. On movement of yoke 19 about pivot 20, caused by pressure of soda lever 21 at soda lever end 22, soda yoke portion 42 presses against the soda actuator thereby opening the soda valve.

Thus it can be seen that the valves in question are easily opened and closed with a minimum of effort. Moreover,-in view of the fact that valve closures 11 are upstream of valve seats 12, the normal pressure in lines 5 and 6 and chambers 10 tends to keep them tightly sealed.

However it has been found preferable to have some form of assistance to actuators 13 (and hence yokes 18 and 19) in returning to the closed position. This is provided by return housing 28 having bores 29 therein. Springs 31 are in bores 29 and spacers 30 are partially in bores 29 and extend out and touch actuators 13 on the side of actuators 13 opposite that at which yokes 18 and 19 contact them.

Thus it can be seen that upon pivotal movement of yokes 18 or 19, spacer 30 is forced to the left (as shown in FIG. 6) against the urging of springs 31 while the valves are in their open position. Upon release of the yokes, the pressure of spring 31 urges spacers 30 to the right (as shown in FIG. 6) causing the yokes and actuators to return to their closed positron.

In a preferred embodiment of the invention, yoke bearing portion 41 is provided with recess 32 into which the actuator controlling the syrup valve fits. As can be best seen in FIG. 4, this permits the soda valve to open first thereby aiding in preventing sticking of the syrup to the dispensing portion of the device.

Syrup passage 25 and soda passage 26 lead from valve seats 12 to the mixing and dispensing portion of the device. Flow adjusters 27 are mounted in passages 25 and 26 to permit adjustment of the rate of flow of each component of the mixed beverage. Syrup passage 25 leads to syrup outlet 33 located substantially in the center of dispensing section 47 of the device.

Soda passage 26 leads to soda outlet 34 adjacent the periphery of dispensing section 47. Beneath soda outlet 34 is dispersing disc 35 containing dispersing channel 37 in a circle substantially concentric with the periphery of disc 35. Dispersing holes 36 extend from the bottom of channel 37 to dispersing recess 38 formed by the underside of dispersing disc 35 and abutment 45 spaced therefrom.

Thus the soda flows through soda passage 26 out soda outlet 34 into dispersing channel 37. As it flows around the dispersing channel 37, it passes through dispersing holes 36 and into dispersing recess 38. It then flows out dispersing recess 38 around the edge of abutment 45.

On the other hand, the syrup flows through syrup passage 25 and through axial opening 46. Thus the soda surrounds the syrup and effectively mixes with it while at the same time preventing the syrup from sticking to dispensing shield 39. The soda, being much more fluid, washes the inner wall of shield 39, keeping it substantially clean at all times. This effect is increased by the use of recess 32 in bearing portion 41 of yoke 18 which, as heretofore described, causes the soda valve to open before the opening of the syrup valve.

In the preferred form of the device, axial opening 46 is located at the center of central core 44.

While in the foregoing specific description of the invention and its various embodiments reference has been made to soda and syrup, it is to be understood that these terms are used in their representative sense only. Thus the dispenser is suitable for use with any fluids. Hence the terms soda and syrup as used both in the specification and in the claims are to be broadly construed to include any other fluids.

While only a limited number of specific embodiments of the present invention have been disclosed, it is nonetheless to be broadly construed and not to be limited except by the character of the claims appended hereto.
